Course and Leg Identifier
The Weems and Plath, Course and Leg Identifier is a marine plotter perfect for expanding square patterns and sector pattern searches. Also known as a Search Pattern Slide Rule or Coast Guard Plotter, this marine plotter tool is a “must have" for active duty Coast Guard, auxiliarists, or anyone who might have to run a search pattern.
The Course and Leg Identifier quickly calculates heading and run time for each leg of either an expanding square pattern or sector pattern search. The marine plotter gives you more time to focus on your search.
